Birds have always had Jake's interest. His uncle had taken him fishing one time, and that's when he first spotted the bird in real life. He watched it as it flew close to the water and attempted to catch a fish in it's giant mouth. Jake realized It was successful when he saw a fish tail flopping in its mouth.
This got Jake thinking how interesting it would be to have that kind of maw. He looked in the mirror to try and imagine how he would look. It was appealing enough just imagining how it would look on him.
With the thought, Jake sat at his desk with his laptop and typed in the box pelican beak. After filling the box, another appeared in front of it. This must be the details of the transformation, he thought. Thinking about it, he decided he would need to alter reality so that he won't be uncomfortable around other humans. Other than that, what else was to change. He filled the box with alter reality and hit enter.
The monitor displayed "Change in progress... Please wait."
At this point Jake wanted a good look at this, so he rushed to the mirror. He didn't notice anything in the following minute until he saw a splatch of yellow on his lip. He tried touching it. It's texture was not a soft wrinkle like a lip, but rough and smooth... Like a beak. Jake's eyes had widened as he saw what he had gotten himself into. At that moment, his lips started stretching wide across his checks still yellowing and changing texture. Once his lips were sprawled across his checks, his jaw bones started spreading outward to support his new "feature". His Wife lips then started pushing out his face bringing his nose with him. Staring in disbelief, he watched as his nose flattened, leaving only his nostrils flared withe the ever changing texture of his face. The yellow had spread all the way across his jaw, and as one last surprise, his skin from his throat expanded, leaving it stretchy enough to swallow a while fish.
Jake couldn't believe what he saw. His own face had bloated into an animals. He examined a bit closer, feeling his lips all the way down to his throat. When he tried to talk, his lips would still move naturaly as if he still had a human face. He even made facial expressions to see how they differed. He had to admit it, it looked good in a weird way. He had managed to smile with his beak. Maybe he finally found his own kink.
Looking back at his laptop now with the display "Transformation complete." Jake excited out of the screen to see what other options he had.
